I would take it by your local auto store, most of them will get their Actron Scan tool and scan it for you for free, they will let you know whatever code it has stored.
As for your stall problem..
I take it you are over 100k miles?
If so have you ever had your fuel filter changed?
I'd do that, and then have all 6 of those fuel injectors swapped for some re-manufactured ones.
That or have a shop flush them professionally for you, I'm betting you will notice a big difference after getting this done.
I say this because I had a similar stall problem for years, and I found out I had two bad injectors, my car was at 134k when it finally died due to the fuel injectors.
As for the car wanting to go on its own, I read about that somewhere, I believe it may have to do with the Idle Air Control Sensor, the Throttle Position Sensor, or maybe it was the Mass Airflow Sensor.
The IAC & MAF can be easily cleaned off if they are a bit carbon fouled.
Just throwing some ideas out there, I am no mechanic, so maybe somebody else out there knows how to better help you.

They had to mean the MAF Sensor as imidazol97 mentioned.
That will be attached to the throttle body, and should be easy to remove, it should have 2-3 screws.
It can be cleaned with MAF Cleaner available at any auto part store, just DO NOT touch the little metal elements you will see once you remove it, or damage them in any way.
I'd also consider having the EGR cleaned, as imidazol had another good suggestion, I have a 96' Park Ave and had some rough idle issue for a long time, I found out my MAF was a little dirty, my EGR was occasionally sticking open due to so much carbon build up.
I also had a Idle Air Control Valve that was carbon fouled, so you may want to have it cleaned as well.
Here is a pic of what it looks like.
Last, but not least, if the car has over 100k miles on it, consider having the fuel injectors flushed, if not swapped out for 6 re-manufactured ones, you should be able to get 6 of them for 160.00-180.00.
#381 of 463 PO-401 (Smog test) that cant be fixed?
Sep 19, 2011 (8:23 pm)
Hi guys, I have a gorgeous diamond white 2000 Ultra with all options, and about 115K on the clock, and its great, but several weeks ago it lost the #3 fuel injector and set that code, so into the shop it went. They replaced the injector and also fixed a small oil leak they found by replacing the intake manifold, and S.C.gasket, they also did a coolant flush.
Now the problem started, on the way home from the shop, and the car running great, it set the code PO-401. My tester reads that as "EGR insufficient flow" (This is a first). So back it went to the repair and smog shop. After 3 weeks in the shop, they say its operating fine, including the EGR system, but the computer will reset the PO-401 ever time its driven. GM has no computer flash (re-programing ?) for this code.
Everything in the EGR system was replaced, some items twice, plus all lines cleaned. Even the intake manifold was removed again to make sure the new gaskets were not at fault.
It has never had a PO-401 code before.
Any ideas? I live in Calif and must find a solution.

check for leaks in the exhaust system
check for clogged inlet or outlet ports TO the EGR.
Check for the following conditions:
Vacuum restriction to the MAP sensor. A restriction to the MAP sensor can cause the EGR flow test to fail due to insufficient MAP changes being monitored during the test. Check for objects blocking the vacuum to the MAP sensor. Also check for kinked or pinched MAP sensor vacuum hoses (if equipped.)
Poor connection at PCM or EGR Valve. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, observe the actual EGR position display on the scan tool while moving connectors and wiring harnesses related to the EGR valve. A change in the display will indicate the location of the malfunction.
#383 of 463 How to put in pass. side window channel rubber on 98' buick park ave.
Sep 27, 2011 (9:46 am)
I think I found the right window channel rubber for my 98' park ave. passenger side but want to know how to change it out first so it will work right( I had a tec.. at collision specialists install one on driver side related to a collision) but I got laid off recently and need to do it myself. The window that was fixed used to jump out and raise with trouble till this was done. That's all that was changed on that door.

I have the same car. You just need to find a mechanic that knows how to do it. It is not worth fixing to him, because it will probably cost what the car is worth. I would fix it for my mother.
Anyways, if you ever want to sell the car in the future please email me.

I do know that this info will help you because I have the same problem. Well hope you can save some money.
Here we go. Before, buying the body control module, you should check these six things.
1) check to see if wires come together in the harness
2) check camshaft sensor wires
3) check crankshaft sensor wires (2 and 3 check to see if wires come together in harness)and change and or retape wiring. Insulation wears out and they touch. Follow the wires from the cam and the crank and make sure they are not touching.
4)Check to see in you have a blown amp
5) Check fuel injection wires and make sure there not touching nothing
6) Finally, check on the 1194 Buick recall for the (starter).
The check engine lite would come on for all these problems, especially if its the wiring....sometimes the blank rapidly and then sometimes one or two lights stay lit.
Hope this help everyone out. Pay it forward and let me know the outcome.

#388 of 463 Climate control won't shut off in 96 park ave
Dec 02, 2011 (11:25 am)
When I shut off my 96 park ave the climate control continues to stay on. The AC and heat can be turned off but the exterior temperature display stays there, and the light indicating that the climate control is off stays on also. Now it is draining my battery. Does anyone have any suggestions?
